Shock testing is conducted to accurately measure the fragility of products and to evaluate protective packaging; the data attained during these tests is the key to understanding whether your product is capable of with standing its “real world” environment.
We use a Lansmont Model 23 shock tester in our lab here in Christchurch to impart shocks of up to 5,000G to small to medium products and packages. Wave shapes supported include sine, sawtooth and square pulse.
Shock testing – why it matters.
Mechanical shocks are encountered in every day life for most mobile devices, components and systems. Sure there’s extreme environments like military, navy and avionic equipment but there’s a lot more that we tend to take for granted. Think about how many times you’ve banged, bumped, or bashed your laptop iPad, or phone – each impact is exposing the product to shock.
Making sure your product will survive the hard knocks of life is essential to maintaining brand loyalty. Whether you’re looking to qualify your product to one of the standards listed below, or improve your product by assessing it’s fragility we recommend shock testing as part of your product test regime.
Oh, and if you doubt your end-users are that harsh, think about the supply chain:
